Q: i have a 98 ford escort SE. oil spils out the dipstick. we think its the pressure release valve. sadly we dont know where that is. any imput would be great: as they said, pcv valve. What you're describing is on a turbo- pressure exhaust valve.

Q: Why are pig hearts valves used as replacements for damaged heart valves in humans? Are there any complications and are they still used today?: Biological valve is made of human or animal tissue. These valves last 12 - 15 years, but you may not need to take blood thinners for life. Human body has a tendency to reject foreign material such as porcine valve. Medication can be used to retard this effect, but is not always successful. Biologic porcine heterograft - harvested aortic valve of pig that is preserved in glutaraldehyde and mounted on specially designed sewing ring. (Carpentier - Edwards/ Hancock/ Medtronic) Tissue valves are also made from 16 to 18 months old calves and harvested aortic valve from human cadaver.

Q: In my condo, I have what appears to be a water relief valve of some sort right after my water inlet pipe. It's after the water cutoff valve. It's not the water heater relief valve. It has a leak, not bad, just a drip right now. It looks like a half baseball sticking out of the main inlet pipe with a bolt in the center of it. I've tried to tighten it but that makes the leak worse. First, what is this. Second, Is there an obvious fix to this. Third, if I have to get it replaced, what model/manufacturer can I get so that this doesn't happen for a long while. My plumbing is short of fifteen years old.: It sounds like a pressure reducing valve. As you tighten that bolt it increases the pressure and made it leak more.It's probably not any good. I think if you go to a home center you'll find one . probably a Watts brand. They seem to be more prolific. Not hard to change.

Q: when heater heats water there is a small leak thru the releif valve. need answrers to possible reasons for malfuntion. leak is not continous.: they start to blow off at 30-35 psi your talking about temperature relief that is indicated on the tag. open it up a tad and let it slowly splash out (not fully open) see if it drips a few minutes afterward if it does replace it.

Q: Steam is a gaming network and valve is a company, but what else? I think that it might be nothing; they both suck at working.: I don't understand this question fully, but I think you like my answer: Steam is a software for gaming articles, but it also meaning gas on another word. Valve (www.google.rs/search?q=Valvehl=srclient=firefox-ahs=SCurls=org.mozilla:en-US:officialprmd=imvnssource=lnmstbm=ischei=8zHfTr2iIsKnhAeTy-yVBQsa=Xoi=mode_linkct=modecd=2ved=0CCgQ_AUoAQbiw=800bih=393) is a legal company, same as meaning the link I put there. Hope it helps! :)

Q: what are the factors should be know to select a control valve for specified application: There are numerous articles online that address this question from choosing the correct size to the correct actuator. Here are just a few:

Q: what is a foot valve? how does it look? what is the application in petrochemical companies?: A foot valve is placed at the bottom of a suction pipe, which could be used to drain a large container of liquid. The foot valve is a one-way valve (check valve) that prevents the liquid from draining back into the container.

Q: What are the function of reed valves on a motorcycle?: there are quite a few types,reeds/reed valve/disc valve..all 2 strokes have some sort of reed system...idea is that fuel is sucked past the reeds,these then close letting the fuel travel where it needs to go,opening when its time to suck fuel in....and so on

Q: 1995 Yukon need valve lash adj- how and hat tools?: remove valve covers, watch front left two lifters and turn engine, by bolt that holds harmonic dampener to front of crankshaft, so mark on dampener lines up with mark on front cover. If rocker arms do not move as marks line up engine should be on top dead center number 1 cylinder. Now you can adjust exhaust valves 1, 3, 4, 8 and intake valves 1, 2, 5, 7 [ odd numbers are on the left bank from the front 1,3,5,7 even on the right bank from the front 2,4,6,8]. Adjust by turning nut in rocker arm out until movement is felt than tighten until all movement is gone and tighten one turn more. After done with the first eight valves turn engine over one full turn till marks line up again. Then adjust exhaust valves 2,5,6,7 and intake valves 3,4,6,8 the same way.
